Introduction: Out-of-hospital cardiac arrest (OHCA) remains a highly morbid public health problem. Despite improving practices and clear guidelines, mortality from this condition remains high at 90%, with survivors often suffering from poor neurologic outcomes. To determine the feasibility of quality improvement collaboratives to narrow gaps between evidence-based practice and patient care for OHCA, we conducted a pilot study of the AHA Resuscitation Collaborative. Methods: Eight emergency medical service agencies participated in the quality improvement collaborative pilot project. We identified several OHCA performance measures to assess the quality of care, guide collaborative activities, and monitor change in performance over time. Over the course of four learning sessions, participants were trained in quality improvement and performance measurement, analyzed performance measure results, and shared successes and challenges. Results: Five remaining agencies underwent the process outlined in Figure 1. Adherence to performance measures, including compression rate compliance (Figure 2), improved over the course of the collaborative. Compression rate compliance in Figure 2 corresponds to the process improvement efforts of the Chesapeake Fire Department with achievement of goals for optimal range of chest compression rate between 100 and 120 compressions per minute during resuscitations. Conclusion: As demonstrated in Virginia, the collaborative approach was an effective framework to improve OHCA care. Improvement in performance measures, the evident commitment of dedicated peers and colleagues, consistent collaboration, and the effective diffusion of best practices all support the continued use of this model.

Background and Objectives: It is estimated that over 200,000 adults experience in-hospital cardiac arrest each year. Overall survival to discharge has remained relatively unchanged for decades and survival rates remain at about 20% (Elenbach et al., 2009). Get With The Guidelines-Resuscitation (GWTG-R) is an in-hospital quality improvement program designed to improve adherence to evidence-based care of patients who experience an in-hospital resuscitation event. GWTG-R focuses on four achievement measures. The measures for adult patients include time to first chest compression of less than or equal to one minute, device confirmation of correct endotracheal tube placement, patients with pulseless VF/VT as the initial documented rhythm with a time to first shock of less than or equal to two minutes, and events in which patients were monitored or witnessed at the time of cardiac arrest. The objective of this abstract is to examine the association between hospital adherence to GWTG-R and in-hospital cardiac arrest survival rates. Methods: A retrospective review of adult in-hospital cardiopulmonary arrest (CPA) patients (n=1849) from 21 Michigan, Illinois, and Indiana hospitals using the GWTG-R database was conducted from January 2014 through December 2014. This study included adult CPA patients that did and did not survive to discharge. Results: The review found that hospitals that had attained 84.6% or higher thresholds in all four achievement measures for at least one year, which is award recognition status, had a significantly improved in-hospital CPA survival to discharge rate of 29.6%. Hospitals that did not obtain award status had a CPA survival to discharge rate of 24.3%. The national survival rate for in-hospital adult CPA survival to discharge is 20%. Hospitals that did not achieve award recognition status still demonstrated improvement in survival rate when compared to the national survival rate, indicating the importance of a quality improvement program such as GWTG-R. No significant difference was found between in-hospital adult CPA survival rate and race between GWTG-R award winning and non-award winning hospitals. Hospitals that earned award recognition from GWTG-R had a survival to discharge rate of 30.2% for African Americans and 29.6% for whites. Hospitals that were did not earn award recognition from GWTG-R had a survival to discharge rate of 20.0% for African Americans and 20.1% for whites. Conclusions: Survival of in-hospital adult CPA patients improved significantly when GWTG-R measures are adhered to. Survival of in-hospital adult CPA patients also improves with implementation of GWTG-R. It is crucial that hospitals collect and analyze data regarding resuscitation processes and outcomes. Quality improvement measures can then be implemented in order to assist with improving in-hospital CPA survival rates.

Impedance Threshold Device

Introduction: Maximizing outcomes after cardiac arrest depends on optimizing a sequence of interventions from collapse to hospital discharge. The 2005 American Heart Association (AHA) Guidelines recommended many new interventions during CPR (‘New CPR’) including use of an Impedance Threshold Device (ITD). Hypothesis: The combination of the ITD and ‘New CPR’ will increase return of spontaneous circulation (ROSC) and hospital discharge (HD) rates in patients with an out-of-hospital cardiac arrest. Methods: Quality assurance data were pooled from 7 emergency medical services (EMS) systems (Anoka Co., MN; Harris Co., TX; Madison, WI; Milwaukee, WI; Omaha, NE; Pinellas Co., FL; and Wake Co., NC) where the ITD (ResQPOD®, Advanced Circulatory Systems; Minneapolis, MN) was deployed for >3 months. Historical or concurrent control data were used for comparison. The EMS systems simultaneously implemented ‘New CPR’ including compression/ventilation strategies to provide more compressions/min and continuous compressions during Advanced Life Support. All sites stressed the importance of full chest wall recoil. The sites have a combined population of ~ 3.2 M. ROSC data were available from all sites; HD data were available as of June 2007 from 5 sites (MN, TX, Milwaukee, NE, NC). Results: A total of 893 patients treated with ‘New CPR’ + ITD were compared with 1424 control patients. The average age of both study populations was 64 years; 65% were male. Comparison of the ITD vs controls (all patients) for ROSC and HD [Odds ratios (OR), (95% confidence intervals), and Fisher’s Exact Test] were: 37.9% vs 33.8% [1.2, (1.02, 1.40), p=0.022] and 15.7% vs 7.9% [2.2, (1.53, 3.07), p<0.001], respectively. Patients with ventricular fibrillation had the best outcomes in both groups. Neurological outcome data are pending. Therapeutic hypothermia was used in some patients (MN, NC) after ROSC. Conclusion: Adoption of the ITD + ‘New CPR’ resulted in only a >10% increase in ROSC rates but a doubling of hospital discharge rates, from 7.9% to 15.7%, (p<0.001). These data represent a currently optimized sequence of therapeutic interventions during the performance of CPR for patients in cardiac arrest and support the widespread use of the 2005 AHA CPR Guidelines including use of the ITD.

Introduction: Cardiac arrest is an urgent situation that, despite the improved resuscitation capabilities, the survival rate of out-of-hospital cardiac arrest victims remains low.Aim: Τo investigate the survival rate of the incoming patients with cardiac arrest in the cardiology infirmary of the emergency department of a public hospital.Material-Method: The study included 210 patients who were transferred pulseless and breathless at the cardiology infirmary of the emergency department of “Tzaneio” Hospital, Piraeus, during the period April 2017 - November 2018. Data was collected from the National Center of Emergency Dispatch's printed forms, as well as from the patients’ admission book of the emergency department.Results: More than 10% (11.9%) of patients with cardiac arrest returned to spontaneous circulation in the emergency department, of which 16% was discharged. Patients with known cardiac history, (p=0.002), with a shockable rhythm (p<0.001), and especially ventricular fibrillation (p<0.001) upon arrival at the emergency room, and patients who were defibrillated at the ambulance during admission and at the emergency room, were more likely to survive (p<0.001). No statistically significant correlation was found between the factors studied and survival after cardiac arrest, in the group of patients that were discharged.Conclusions: The survival rate of the incoming patients with cardiac arrest at the emergency department of “Tzaneio” Hospital, Piraeus, was low. As for most health systems, this issue constitutes a fairly complex public health problem. Cardiopulmonary resuscitation and corresponding guidelines require further improvement in order for the survival rates of out-of-hospital cardiac arrest patients to increase.

Introduction: Many regions around the world have reported declining survival rates from out-of-hospital cardiac arrest (OHCA) during the COVID-19 pandemic. This has been attributed to COVID-19 infection and overwhelmed healthcare services in some regions and imposed social restrictions in others. However, the effect of the pandemic period on CPR quality, which has the potential to impact outcomes, has not yet been described. Methods: A retrospective observational study was performed using data collected in an established OHCA registry in Victoria, Australia. During a pre-pandemic period (11 February 2019-31 January 2020) and the COVID-19 pandemic period (1 February 2020-31 January 2021), 1,111 and 1,349 cases with attempted resuscitation had complete CPR quality data, respectively. The proportion of cases where CPR targets (chest compression fraction [CCF]≥90%, compression depth 5-10cm, compression rate 100-120 per minute, pre-shock pauses <6 seconds, post-shock pauses <5 seconds) were met was compared between the pre-pandemic and pandemic periods. Logistic regression was performed to identify the independent effect of the COVID-19 pandemic on achieving CPR targets. Results: The proportion of arrests where CCF≥90% significantly decreased during the pandemic (57% vs 74% in the pre-pandemic period, p<0.001) as did the proportion with pre-shock pauses <6 seconds (54% vs 62%, p=0.019) and post-shock pauses <5 seconds (68% vs 82%, p<0.001). However, the proportion within target compression rate significantly increased during the pandemic (64% vs 56%, p<0.001). Following multivariable adjustment, the COVID-19 pandemic period was independently associated with a decrease in the odds of achieving a CCF≥90% (adjusted odds ratio [AOR] 0.47 [95% CI 0.40, 0.56]), a decrease in the odds of achieving pre-shock pauses<6 seconds (AOR 0.71 [95% CI 0.52, 0.96]), and a decrease in the odds of achieving post-shock pauses<5 seconds (AOR 0.49 [95% CI 0.34, 0.71]). Conclusion: CPR quality was impacted during the COVID-19 pandemic period which may have contributed to a decrease in OHCA survival previously identified. These findings reinforce the importance of maintaining effective resuscitation practices despite changes to clinical context.

Introduction: The 2010 American Heart Association Guidelines stated that “cardiopulmonary resuscitation prompt and feedback devices may be useful for training rescuers and may be useful as part of an overall strategy to improve the quality of CPR for actual cardiac arrests.” We sought to assess the effect of one such device on OOHCA outcomes in a large, urban setting. Methodology: Out-of-hospital cardiac arrest data from two consecutive twelve-month periods was analyzed: August 1, 2010 - July 31, 2011 (control) and August 1, 2011 - July 31, 2012 (CPR feedback). During the CPR feedback period, defibrillators capable of providing real-time audible and visual CPR feedback were added to standard prehospital resuscitation care. Results: There were 850 and 748 bystander witnessed arrests of cardiac etiology in the two periods. Patient and arrest characteristics for the two groups did not differ with respect to age, gender, race, response time, bystander witnessed status, or the frequency of bystander CPR. As compared to the control period, the addition of real-time CPR feedback resulted in a significant improvement in immediate outcomes: return of spontaneous circulation, or ROSC (39.59% vs. 47.71%, p=0.001); sustained ROSC (31.17% vs. 36.14%, p= 0.037). However, there was no improvement in survival to hospital admission (24.88% vs. 25.32%, p=0.85) or survival to hospital discharge (5.63% vs. 6.72%, p=0.43). In addition, among those survivors for whom neurologic status is known, the addition of CPR feedback did not significantly change the proportion of survivors considered neurologically intact (70.37% vs 65.63%, all p=0.78). Conclusions: The addition of real-time CPR feedback to a large urban EMS system’s resuscitation care resulted in significant improvements in immediate survival but did not affect overall survival rates. It is also possible earlier introduction of these devices (through their use by first responder and/or earlier arriving basic life support units) may provide greater benefit. Further data analysis is required to determine the specific effect of CPR feedback devices on long-term survival and to optimize their use in resuscitation care.

Background Mathematical optimization of automated external defibrillator (AED) placement may improve AED accessibility and out‐of‐hospital cardiac arrest (OHCA) outcomes compared with American Heart Association (AHA) and European Resuscitation Council (ERC) placement guidelines. We conducted an in silico trial (simulated prospective cohort study) comparing mathematically optimized placements with placements derived from current AHA and ERC guidelines, which recommend placement in locations where OHCAs are usually witnessed. Methods and Results We identified all public OHCAs of presumed cardiac cause from 2008 to 2016 in Copenhagen, Denmark. For the control, we computationally simulated placing 24/7‐accessible AEDs at every unique, public, witnessed OHCA location at monthly intervals over the study period. The intervention consisted of an equal number of simulated AEDs placements, deployed monthly, at mathematically optimized locations, using a model that analyzed historical OHCAs before that month. For each approach, we calculated the number of OHCAs in the study period that occurred within a 100‐m route distance based on Copenhagen’s road network of an available AED after it was placed (“OHCA coverage”). Estimated impact on bystander defibrillation and 30‐day survival was calculated by multivariate logistic regression. The control scenario involved 393 AEDs at historical, public, witnessed OHCA locations, covering 15.8% of the 653 public OHCAs from 2008 to 2016. The optimized locations provided significantly higher coverage (24.2%; P <0.001). Estimated bystander defibrillation and 30‐day survival rates increased from 15.6% to 18.2% ( P <0.05) and from 32.6% to 34.0% ( P <0.05), respectively. As a baseline, the 1573 real AEDs in Copenhagen covered 14.4% of the OHCAs. Conclusions Mathematical optimization can significantly improve OHCA coverage and estimated clinical outcomes compared with a guidelines‐based approach to AED placement.

Background Bystander cardiopulmonary resuscitation (CPR) is a critical intervention to improve survival following out‐of‐hospital cardiac arrest. We evaluated the quality of bystander CPR and whether performance varied according to the number of bystanders or provision of telecommunicator CPR (TCPR). Methods and Results We investigated non‐traumatic out‐of‐hospital cardiac arrest occurring in a large metropolitan emergency medical system during a 6‐month period. Information about bystander care was ascertained through review of the 9‐1‐1 recordings in addition to emergency medical system and hospital records to determine bystander CPR status (none versus TCPR versus unassisted), the number of bystanders on‐scene, and CPR performance metrics of compression fraction and compression rate. Of the 428 eligible out‐of‐hospital cardiac arrest, 76.4% received bystander CPR including 43.7% unassisted CPR and 56.3% TCPR; 35.2% had one bystander, 33.3% had 2 bystanders, and 31.5% had ≥3 bystanders. Overall compression fraction was 59% with a compression rate of 88 per minute. CPR differed according to TCPR status (fraction=52%, rate=87 per minute for TCPR versus fraction=69%, rate=102 for unassisted CPR, P <0.05 for each comparison) and the number of bystanders (fraction=55%, rate=87 per minute for 1 bystander, fraction=59%, rate=89 for 2 bystanders, fraction=65%, rate=97 for ≥3 bystanders, test for trend P <0.05 for each metric). Additional bystander actions were uncommon to include rotation of compressors (3.1%) or application of an automated external defibrillator (8.0%). Conclusions Bystander CPR quality as gauged by compression fraction and rate approached guideline goals though performance depended upon the type of CPR and number of bystanders.

Background: Cardiac arrest is a major public health issue worldwide. In Japan, the regional disparity of the number of physicians per 100000 population is also a major public health problem. However, it is unknown whether there is the relationship between favorable neurological outcome in patients with out-of-hospital cardiac arrest (OHCA) due to cardiac etiology and this regional disparity. The aim of the present study was to clarify this relationship using the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of OHCA. Methods: From the data of the All-Japan Utstein Registry between 2011 and 2015, we included adult patients who had OHCA due to cardiac etiology. 47 prefectures of Japan were divided into quartiles on the basis of the number of physicians in each prefecture, reported by Ministry of Health, Labor and Welfare in Japan. In addition, study patients were divided into four groups based on these quartiles. We compared favorable neurological outcome at 30 days after OHCA in each group, using the multivariable logistic-regression analysis. Results: Four quartile ranges of the number of physicians were set for this study (Figure). Moreover, of the 629,471 OHCA victims between 2011 and 2015, 358,993 met the inclusion criteria. Figure represented favorable neurological outcome at 30 days after OHCA in each quartile. In the multivariable analysis, the adjusted odds ratios for Quartile 2, Quartile 3 and Quartile 4 compared with Quartile 1 for favorable neurological outcome at 30 days after OHCA was 0.971 (95%CI 0.918- 1.027; P=0.307), 1.011 (95%CI 0.956- 1.069; P=0.703) and 0.850 (95%CI 0.809- 0.893; P<0.001), respectively. Conclusion: The regions in which the number of physicians per 100000 population was larger were inferior to the regions in which the number of these was smaller, in terms of neurological benefits in patients with OHCA due to cardiac etiology.

Introduction Long pauses without chest compressions (CC) have been identified in CPR provided by EMS professionals for out-of-hospital cardiac arrest (OOHCA). The 2005 AHA ECC CPR guidelines emphasize CC. The 2005 AHA Basic Life Support (BLS) for Healthcare Professionals (HCP) course introduced a training method with more CPR skills practice during the DVD based course. The purpose of this before/after study was to determine whether CC rates increased after introduction of the 2005 course. Methods This urban EMS system has 400 cardiac etiology OOHCA events annually. A convenience sample of 49 continuous electronic ECG recordings of VF patients was analyzed with the impedance channel of the LIFEPAK 12 (Physio-Control, Redmond WA) and proprietary software. A trained researcher verified the automated analysis. Each CC during the resuscitation attempt and pauses in CC before and after the first defibrillation shock were noted. The time of return of spontaneous circulation (ROSC) was determined by medical record review and onset of regular electrical activity without CC. Medical records were reviewed for outcome to hospital discharge. The EMS patient care protocol for VF was changed on July 1, 2006 to comply with the 2005 AHA ECC guidelines. Cases were grouped by the OOHCA date: 9/2004 to 12/31/2006 (pre) and 7/1/2006 to 4/21/2007 (post). EMS personnel began taking the 2005 BLS for HCP course during spring 2006. Monthly courses over 3 years will recertify 1500 personnel. Results 29 cases were analyzed from the pre group and 20 from the post group. Compressions per minute increased from a mean (±SD) of 47 ± 16 pre to 75 ± 33 post (P < 0.01). The mean count of shocks given per victim decreased from 4.5 ± 4.0 pre to 2.8 ± 1.8 post (P < 0.04). The CC pause before the first shock was unchanged (23.6 ± 18.4 seconds to 22.1 ± 17.9). but the CC pause following that shock decreased significantly from 48.7 ± 63.2 to 11.8 ± 22.5 (p=0.008). Rates of ROSC (55% pre, 50% post) and survival to discharge (15% pre, 13% post) were similar. Conclusion Following introduction of the 2005 BLS for HCP course and the EMS protocol change, the quality of CPR delivered to victims of OOHCA improved significantly compared with pre-2006 CPR. The sample size was too small to detect differences in survival rates.
